SU129159A1 - Sitcha or cap plate for carrying out processes of heat and mass transfer - Google Patents

Description

The known sieve or cap plates for carrying out heat and mass transfer processes do not allow a sharp increase in the vapor (gas) velocity in the free cross section, and at a high gas flow rate there is a sharp increase in the entrainment of liquid with gas.

The described ne plate has these drawbacks, as it allows to increase the vapor (gas) velocity in the free section of the column, as well as drastically reduce the entrainment of liquid by gas, allowing for a wide variation in the gas (vapor) and liquid velocities.

The performed laboratory experiments confirmed the advantages of the described plate. Visually, it was noted that the amount of liquid at different gas velocities on the plate of the proposed design is maintained more permanently and relatively insignificantly depends on the degree of irrigation.

The comparison showed that the plate of the described construction continued to work steadily, when in the same conditions a full unag was observed on a plate of known construction.

FIG. 1 shows schematically a column in section and plan with a plate; in fig. 2 knot drain unit tare.chki.

The plate is provided with an inlet pocket 1, a partition for backwater, foam 2, a drain pipe 3 with an overflow pocket 4, which has a separating partition 5, overflow threshold 6 and a horizontal platform 7 for providing separation of the gas-liquid (vapor-liquid) emulsion.

To increase the separation area of the foam or the emulsion, the retaining partition can be additionally equipped with one or two slots with inclined channels that do not reach the inner wall of the column.
